What Indy Games do you own right now?
I have:
Indiana Jones & the Emperor's Tomb (Xbox)
Indiana Jones & the Infernal Machine (PC)
Indiana Jones & his Greatest Adventures (SNES)
and a demo of Indiana Jones Desktop Adventures (PC)

Just for kicks I've played IM on N64, some ROMs of Indy games on PC and NES, and I've seen the ToD arcade game at a movie theater once. I don't remember what theater and I didn't have change to play it...

FoA fills only 1/4 of the CD-Rom. There's room for LC and DA and whatever else if Lucasarts pressed a reissue! Like the Monkey Island Madness disc (I and II). That way I could toss the LC floppys and FoA audio patch files that never worked.

I should note that i am only played a few of them, mostly IJ&FOA, IJ&DA, IJ&IM, and IJ&ET, the rest i have played but with college i don't have much time, and i would prefer to keep them in good condition.

I'd like to think that I play all these games all the time but with school and work I don't usually have a tone of time to play with. I'd even go as far as saying that I play the fan games more than the games that I've actually purchased. Not that I don't like them, but if I sit down to (FOA) or (ET) I get immersed into the game and end up not getting my work done.

Indiana Jones and the Fate of Atlantis (PC) - CD only
Indiana Jones and the Infernal Machine (PC, N64) - box/manual for both
Indiana Jones and the Emperor's Tomb (PC, PS2) - box/manual for both
2 Indiana Jones' Greatest Adventures (SNES) - one with box/manual, one cart only

I have all home games EXCEPT "Revenge of the Ancients" (on my want list). Also have the pinball machine, the Atari stand-up TEMPLE OF DOOM machine as well as both the German 1/2 cabinet Slot machine and the full-cabinet machine from the UK.

Unless someone knows of something I've missed. If so - please post so I can start hunting!
